BACKGROUND: The growth of elderly population increased the need for oral health care. Elderly patients with poor teeth alignment needs more attention with orthodontic treatment METHODS: Elderly patients visiting department of orthodontics, Kangdong Sacred Heart Hospital between 2000-2004 were treated with fixed appliances in one or both dental arches. Treatment plans were different from than that of younger patients and included uncommon and strategic removals of teeth and prosthesis. RESULTS: There was decrease in orthodontic treatment forces with increasing age, and the observation made from this study was favorable in the patients' as well as in the orthodontist's, point of view. It was possible to move the remaining teeth considerably, and the retention was made with various fixed appliances. CONCLUSIONS: Orthodontic treatment is not limited by patient age. However, it is wise not to extend treatment goals too far beyond the patients' objective needs

BACKGROUND: Hypertension is one of the common diseases which family physicians encounter to manage. Various research proved that appropriate aerobic exercise had effect on lowering blood pressure efficiently. This study was to find out the status of exercise, the change of exercise according to time and its predicting factors in hypertensive patients. METHODS: A total of 193 of the followed-up hypertensive patients of family physicians in Seoul and kyoungkido from May 11, 2001 to June 10, 2001 were interviewed by doctor according to the previously designed structured questionnaire. RESULTS: Eighty two patients (42.57) were male and mean and was 57.4 +/- 9.9 fears. Using Kaplan-Meier's method, 8% of non-exercise group (N= 115) in diagnosing hypertension started exercise after 1 fear and 40%, after 5 years. Otherwise, 5% of exercise group(N=78) stopped exercise after 1 year and 30%, after 5 years. The characteristics of 5 exercise groups according to sex, age, level of education and adequacy of exercise showed significant difference. In average blood pressure, lately started group showed the lowest (137/84 mmHg) and non-exercise group, the highest (146/91 mmHg) In the degree of recommendation. sporadic group showed the highest and non-exercise group, the lowest which showed significant difference (p =0.0024) . CONCLUSION: I conclude that lately started group among non-exercise group and continuous exercise group were mainly affected by recommendation to exercise of physician. As well as exercise, other nonpharmacologic treatment should be promoted by physician as an important strategy for treatment of hypertension.

End-to-side neurorrhaphy had been firstly reported at the beginning of this century, but no further clinical reports have been released. In some cases of end-to-end neurorrhaphy, donor nerve incision or even sacrification is inevitably necessary. In doing end-to-side neurorrhaphy, has not been widely accepted because previous results were not satisfactory. The purpose of this study is to evaluate the applicability of end-to-side neurorrhaphy in rats. Twenty female Sprague-Dawley rats, weighing approximately 200-250 g(232.50+/-12.6g) were used. In 10 rats, their right and left peroneal nerves were cut and the distal end of peroneal nerves were end-to-side neurorrhaphied to the tibial nerve. On the right side, the epineurium was left intact and on the left side, it was removed. The proximal end of peroneal nerves were imbedded in the thigh muscle. After 6 months, eletrophysiologic tests, including nerve conduction velocity, the amplitude and the areas of action potential of the tibial cranial muscle were done and then all rats were sacrificed for histologic analysis. The other 10 offspring rats were raised and used for control group. The mean weight of the tibial cranial muscle was 1.74(+/-0.30)g on the right side, 1.54(+/-0.31)g on the left side and 1.97(+/-0.28)g in the control group, which was statistically not significant. The number of muscle fibers in x 100 magnification was 106.10(+/-4.28) on the right side, 109.67(+/-4.69) on the left side and 107.80(+/-4.64) in the control group, which was also not significant. The amplitude and width of muscle action potential were not statistically different among the right side, the left side and in the control group. However, the nerve conduction velocity was bilaterally delayed if compared to control group. In histologic analysis, the presence of epineurium did not impact the results and end-to-side neurorrhaphy were successfully regenerated in all rats. End-to-side neurorrhaphy seem to be a functionally and histologically tolerable alternative when end-to-end neurorrhaphy is not available.

The pulsed laser lithotripsy has been used in the treatment of urinary calculi. We treated 153 patients of stones, via the pulsed dye laser(Technomed Pulsolith) with 7.5 and 6.5 F. rigid ureteroscope between January 1992 and January 1995. Stones were in bladder(4 cases), upper ureter(17), mid ureter(31) and lower ureter(101). The laser lithotripsies were applied for impacted stones and relatively large stones(more than 6 mm) The success rates according to location were 47%(8/17) in upper ureter, 77%(24/31)in middle ureter, 95%(96/101)in lower ureter and 100%(4/4) in bladder and mean success rate was 86% (132/153). There were 21 failures due to upward migration(9 cases), poor visual field(7), laser resistant stone(3) and malfunction of laser(2). Complications were showed in 28 cases that were gross hematuria(16 cases), ureteral perforation(6), fever(4) and ileus(2), but most of them might be related to ureteroscopy rather than laser, and all of them were resolved with conservative management. So laser lithotripsy is safe and effective method of middle and lower ureteral calculi, and upward migration of stones, the major cause of failure may be resolved by use of extracorporeal shock wave lithotripsy and flexible ureteroscope.

PCR implication using the primers for gag, pol and rev genes in BLV (bovine leukemia virus) proviral DNA and syncytium assay were carried out for the Korean native goats experimentally infected with bovine leukemia virus to investigate pathogenesis of BLV in the goats, and to establish a model animal for BLV infection. The oligonucleotide primers used in PCR revealed very high specificity, The minimal amount of FLK-BLV cellular chromosomal DNA to detect the integrated BLV proviral DNA was 10 ng. The peripheral blood lymphocytes from the goat infected with BLV were examined at regular intervals by PCR amplification and syncytium assay. Pol or gag genes were detected in none of three infected goats at the 1st week post-infection (p.i.). At the 4th week p.i., one of three goats showed the amplified gag gene. Thereafter detection rates for the genes were increased, indicating that the BLV proviral genes were integrated in all of the lymphocytes from three goats, at the 16th weeks p.i., when it was evident in syncytium assay that the lymphocytes from all of three goats were infested with infective BLV. Investigating the tissues from the necropsied goats at the 8th month p.i., the amplified BLV proviral genes and infective BLV were detected in all of the peripheral lymphocytes from three infected-goats. Among various tissues examined, the amplified BLV proviral genes were observed in spleen and superficial cervical, mandibular and retropharyngeal lymph nodes, and the infective BLV, in superficial cervical and mandibular lymph nodes. It was assumed that the Korean native goat was quite susceptible to BLV infection, indicating that the goat could be a good model animal for BLV.

We report two cases of vulvar syringorna in a 40-year-old women and a 28-year-old woman who had 2-3mm sized, brownish papules on both valvar areas an l-3rnm sized, yellow-brownish papules on both vulvar ares with yellowish milia-like lesion the surface, respectively. Microscopically the lesions revealed characteristic findings of syrinzoiza However the second case showed a small cystic duct in the papillary dermis, which is lineilly a stratified epithelium and filled with concenteric lamellae of keratin.
